Drought zones have been declared across much of England and Wales, yet Scotland has just registered its wettest-ever May. The warmest British spring in 100 years followed one of the coldest UK winters in 300 years. June in London has been colder than March. February was warm enough to strip on Snowdon, but last Saturday it snowed there.

Welcome to the climate rollercoaster, or what is being coined the “new normal” of weather. What was, until quite recently, predictable, temperate, mild and equable British weather, guaranteed to be warmish and wettish, ensuring green lawns in August, now sees the seasons reversed and temperature and rainfall records broken almost every year. When Kent receives as much rain (4mm) in May as Timbuktu, Manchester has more sunshine than Marbella, and soils in southern England are drier than those in Egypt, something is happening.

Sober government scientists at the centre for hydrology and ecology are openly using words like “remarkable”, “unprecedented” and “shocking” to describe the recent physical state of Britain this year, but the extremes we are experiencing in 2011 are nothing to the scale of what has been taking place elsewhere recently.

Last year, more than 2m sq km of eastern Europe and Russia scorched. An extra 50,000 people died as temperatures stayed more than 6C above normal for many weeks, crops were devastated and hunderds of giant wild fires broke out. The price of wheat and other foods rose as two thirds of the continent experienced its hottest summer in around 500 years.
